About Z31
Z31 is the ICD-10-CM diagnosis code for encounter for procreative management. It belongs to block Z30-Z39 (persons encountering health services in circumstances related to reproduction) and chapter 21 (factors influencing health status and contact with health services). It is a header code, so it can't be reported by itself; one of its 7 subcodes must be used instead.
To report this condition, pick the subcode that matches the documentation: Z31.0 (sterilization), Z31.4 (testing), Z31.5 (counseling), Z31.6 (procreation), Z31.7 (and counseling for gestational carrier), Z31.8 (management) and Z31.9 (unspecified).
The conditions in its Excludes2 note aren't part of Z31, but may be coded alongside it if the patient has both: complications associated with artificial fertilization (N98.-), female infertility (N97.-) and male infertility (N46.-).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
